Preparing Evergreens for Winter

November 16, 2009

All evergreens, and particularly broad leaf evergreens such as boxwood and rhododendron, are susceptible to winter desiccation. Winter desiccation also is referred to as winter burn or winter browning. Desiccation occurs when the evergreen's foliage loses moisture due to the bright winter sun and harsh winter winds. In winter the plants are not able to absorb enough additional moisture from the soil to replace the water that evaporates from the foliage and stems. In addition to making sure the plants are well watered before the onset of winter there are a few other measures homeowners can take to protect the plants.

Secrets of Sooty Blotch and Flyspeck on Apples

September 21, 2009

Sooty blotch and flyspeck may be as old as apples themselves. Drawings of apple varieties from the 1820s clearly show sooty blotch on every fruit. It wasn’t until sprayed-on pesticides, such as lime sulfur and lead arsenate, became popular around 1900 that consumers began to expect to buy apples without a heavy coating of sooty blotch and flyspeck. The cosmetically perfect apples found in today’s supermarkets weren’t common until the middle of the 20th century, when more effective organic fungicides appeared.

May 11, 2009

Spring or early summer is one of the best times of year to test your well. Iowa gets most of its rainfall April through June.

If the upper part of your well is leaky, this contaminated water may enter your well through these defects, bringing contaminants with it. Read more about Spring is a Good Time to Test Well Water
